1 Claim. 1

The present invention relates to a vise jaw construction and it consistsin the combinations, constructions and arrangements of the parts hereindescribed and claimed.

Generally there is provided a vise jaw construction wherein the upperend of one of the conventional jaws of a vise is removed and thenequipped with a pair of upwardly extending removably mounted caps whichact to hold in selected positions various faces of a rotary grippingmember. Novel means is provided for holding the rotary member in theselected positions.

It is accordingly an object of the invention to provide a device of thecharacter set forth which is simple in construction and operation andyet effective and efficient in use.

Another object of the invention is the provision of a device of thecharacter set forth which is inexpensive and easily attached to aconventional vise jaw.

Another object of the invention is the provision of novel means wherebyvaried gripping surfaces may be presented upon one face of aconventional vise.

A further object of the invention is the provision of novel means forrigidly holding a rotary vise jaw, forming a part of the invention, inselected positions.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawing, in which:

Figure 1 is a front elevational view, partly broken away, of anembodiment of the invention,

Figure 2 is a sectional view taken along line 2-2 of Figure 1,

Figure 3 is an isometric view of an element of the invention, and

Figure 4 is a fragmentary sectional view, somewhat enlarged, taken alongline 44 of Figure 1.

Referring more particularl to the drawing, there is shown therein aconventional vise jaw I provided with a centrally disposed recess 11 inthe upper face thereof and having at either side on its upper face avise jaw cap I2 which is connected with the jaw I0 by means of avertically disposed screw I3. The upper ends of the jaw I0 are providedwith semi-cylindrical recesses I 4 and the lower faces of the caps l2are provided with corresponding semi-cylindrical recesses I 5 and r therecesses I4 and I5 coast to receive the outwardly extending axles I 6 ofa rotary jaw generally designated at IT.

Each of the axles I8 is provided with four pa s ipherical indent t ons IEach of the caps I2 is provided with a vertically disposed tubularpassage I9 in the lower end of which is positioned a ball 23 and in theupper end of which is threaded a set screw 2!. A compression spring 22is also positioned in the passage I9 and bears against the ball 20 andset screw 2|.

The member I? is provided with four faces which are at right angles toeach other. One of the faces is flat, as indicated at 23. There is alsoprovided a concave surface 2 5, a surface 25 having a V-shaped indentedgroove 26 and a concave ridged surface 21.

In operation, it will be apparent that the member I? is mounted in thejaw It by first placing the axle I6 within the recesses I4 after whichthe caps I2 are fixed thereon by means of the screws I3 in such mannerthat the axles I6 are received in the recesses I5. The balls 20 are thendropped into the passages l9 after which the springs are placed thereonand the set screws screwed into position to force the balls 20 to engagein one of the recesses I8 in the axles IE to thus hold the same rigidlyin a selected position.

It will thus be seen that four different faces of the member I? may beselectively placed in vertical position upon the inner side of the jawIs. Where it is desired to work upon flat material, the face 23 ispresented in a vertical position on the inner face of the jaw Ill. Whenround work is to be clamped between the conventional jaws It of a vise,the face 24 is presented as particularly shown in Figure 2 of thedrawing. Likewise, when it is desired to fasten a pipe within the vise,the face 2'! is presented upon the inner side of the jaw I6 and, again,with certain work the face 25 with its V-shaped groove may be presentedupon the inner side of the jaw. In order to make the changes it is onlynecessary to loosen the cap screws I3 and the set screws 2! and tothereafter turn the member I? with the fingers until the proper face ispresented upon the inner side of the jaw I0 after which the screws I3and 2! are again tightened.

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claim.

What is claimed .is:

A device of the character described comprising a vise jaw having acentrally disposed recess in the upper end thereof and having asemi-cylindrical recess in the top thereof adjacent each end of thecentral recess, a vise jaw cap removably mounted at either side of theupper end of the vise jaw and each having a semi-cylindrical recess inthe bottom thereof, a revoluble gripping member disposed in said centralrecess and having a pair of outwardly extending axles adapted to bepositioned in the semi-cylindrical recesses in the jaw and in the jawcaps and adjustable means for locking the revol-uble gripping member inselected positions with respect to the inner face of the vise jaw, saidmeans including a plurality of spaced semi-spherical openings intheouter periphery of each of the axles, a vertical passage in each of thecaps in registry with said openings, a ball in the lower end of eachpassage, a compression spring atop each ball and a set screw threadablymounted in the upper end of each passage, said revoluble gripping,member having a plurality of different gripping faces References Citedin the file of this patent UNITED STATES PATENTS 5 Number Number 15102,690 168,030 3963281 adapted to be selectivelypresented at the inner20 Name Date Whiton July 14, 1857 Wanless Mar. 30, 1887 Bovee Nov. 21,1916 Stroh July 26, 1921 Butt Feb.
